Glasses-free days for your child — from lenses worn only while they sleep.

Ortho-k sounds too good to be true to most parents. Press play to see exactly how an overnight lens reshapes the eye's surface, why vision is sharp the next day without glasses, and how it slows nearsightedness from getting worse.

Animated cross-section of a child's eye showing how an overnight ortho-k lens reshapes the cornea A side view of an eye. As the eye grows too long, focus falls in front of the retina and vision blurs. Overnight, a custom ortho-k lens gently flattens the central cornea. The next day, without glasses, central light focuses on the retina while peripheral light focuses in front of it — a signal associated with slower eye growth.

Freedom during the day. Protection for the long run.

Ortho-k is COVE's specialty — we fit and monitor every child with corneal topography, and we'll tell you honestly whether ortho-k, MiSight, Stellest lenses, or another option fits your child best.

Schedule an ortho-k consultation

*Across published clinical studies and meta-analyses, orthokeratology slows axial eye growth by roughly 40–60% compared with single-vision correction — about half, on average. The “two paths” chart is an illustrative example, not a prediction for any individual child. Individual results vary; ortho-k requires proper fitting, nightly wear, and good lens hygiene. COVE's ortho-k lenses are custom-designed from your child's own corneal map. This animation is educational and doesn't replace an exam — schedule an ortho-k consultation with Dr. Karres, Dr. Keller, or Dr. Dennis to see if your child is a candidate.
